Hello.. first post in the Klipsch forums. Been a lurker for a while as I was shopping for speakers. I'm looking for advice as I'm something of a neophyte when it comes to speaker setups. Until now, I've really just used shelf systems, computer speakers, sound bars, etc. Recently I delved back into the vinyl world and purchased a turntable. I've been using it with my computer speakers but wanted to push it up to something better. After doing quite a bit of research, and not wanting to go the full HT route, I chose to go with some Klipsch R-15PM bookshelf speakers and joined them to a Klipsch R-10SW sub. The room I'm using this setup for is approximately 18' x 12' with 10' ceiling. My first question. Upon first usage, I was somewhat disappointed in the sound. The sound was something akin to "muddled". If that makes any sense. I was expecting to hear some higher end highs and of course lower lows considering the sub was included. Everything seemed just kind of middle of the road. Is this to be expected from the R15-PM? Next question, is the R-10SW sub a good match for the R-15PM? Or should I have opted to step up a size (or 2) on the sub? Follow-up question, is there a preferred setting on the sub to make it sound best? I know it should be dialed in, but I'm afraid I'm just not setting it right to begin with.. Any insight or personal experience with this speaker and/or sub combo would be greatly appreciated. Thx
